Investigating
the mould filling characteristics of an injection mould
using mould flow simulation technology highlights potential
problems before they actually occur. This enables our engineers
to develop a practical solution while the mould design proceeds.Flow Analysis

Flow analysis simulates the Filling and Packing phases of the injection molding process to predict the flow behavior of thermoplastic melt. Based on results of the study combined with practical experience Imtech is able to increase the certainty of producing acceptable quality parts.

Flow analysis is also a highly effective tool for identify and solving problems with existing molds.

Improvements in part quality are achieved by refining gate points, the position of weld lines, eliminating gas traps, balancing pressure drops and reducing stress levels.

The holding phase simulates pressurisation of the injection mold cavity after the initial dose of polymer melt has filled the cavity. During the packing phase the cavity is bought up to pressure by forcing more melt through the gate until the gate freezes off when the pressure is released. Results calculated during the packing phase include a refined clamp force prediction, volumetric shrinkage, freeze times and sink marks.3D Simulation
